Note to Self - Java Runtime Environment and Mozilla Firefox on 64-bit Red Hat Linux

(1) Download the JRE from here ( assuming that you're happy to use the Oracle JRE ): -

Java Downloads for All Operating Systems - Recommended Version 7 Update 21

I chose the Linux x64 RPM from the above list: -

http://javadl.sun.com/webapps/download/AutoDL?BundleId=76852

(2) Install the RPM: -

$ rpm -ivh jre-7u21-linux-x64.rpm

(3) Create a symbolic link to the plugin: -

( for non-root user e.g. wasadmin )

$ ln -s /usr/java/jre1.7.0_21/lib/amd64/libnpjp2.so /home/wasadmin/.mozilla/plugins/

( for root )

$ mkdir ~/.mozilla/plugins

$ ln -s /usr/java/jre1.7.0_21/lib/amd64/libnpjp2.so ~/.mozilla/plugins

(4) Restart Firefox

(5) Test Java

(6) Have a nice soothing cup of camomile tea ….
